048965-0006 is a jam nut receptacle circular connector featuring a socket gender configuration with 26 size-20 solder cup contacts arranged in a 16-26 pattern. The connector is constructed with an aluminum alloy shell plated with olive drab chromate over cadmium, and incorporates a grommet seal with strain relief for environmental protection. Key technical characteristics include copper alloy contacts with gold plating, polychloroprene insulator and grommet material, and compliance with MIL-DTL-26482 Series I standards. The connector operates over a temperature range of -55°C to +125°C, supports 500 minimum mating cycles, and achieves IP67 protection at 0.2 bar pressure over 48 hours. With a contact rating of 7.5 A at AWG20, insulator resistance of approximately 5000 MO, and test voltage of 1500 Vrms, this connector is well-suited for military and aerospace applications requiring robust, sealed interconnections in demanding environments.
